the reactivity series

Question 1

what will happen with iron sulphate+sodium?

Answer 1

It will turn into sodium sulphate+iron

This is because of displacement, sodium is stronger than iron

Question 2

what will happen to zinc nitrate+ tin?

Answer 2

it will stay the same because tin is weak and so its not strong enough to displace zinc

Question 3

write the word equation for the answer of magnesium and copper sulphate

Answer 3

magnesium sulphate + copper

Question 4

write the word equation answer for magnesium and lead nitrate

Answer 4

magnesium nitrate + lead

Question 5

write a word equation the answer for magnesium and lead sulfate

Answer 5

magnesium sulfate + lead

Question 6

Tin oxide and copper—»>?

Answer 6

would stay the same so tin oxide+copper

Question 7

Gold and copper oxide—-»>?

Answer 7

it would stay the same so gold+copper oxide

Question 8

Calcium and copper oxide—–»>?

Answer 8

calcium oxide+ copper

Question 9

Where do metals come from?

Answer 9

they can be found naturally e.g gold

they are also made from combined elements, can be found as metal ore

Question 10

How does carbon extract metals

Answer 10

if the metals more reactive than carbon cant be extracted from their ores by carbon.

Question 11

Copper carbonate and carbon—»>?

Answer 11
